The Yellow Lab then turned to the Black Lab and asked "So, why are you here?"

The Black Lab said, "I'm a digger. I dig under fences, dig up flowers and trees. I dig just for the hell of it. When I'm inside, I dig up the carpets, but I went over the line last night, when I dug a great big hole in my owner's couch."

"So, what are they going to do to you ?" the Yellow Lab enquired..

"Looks like I'm losing my balls too," the dejected Black Lab replied.

The Black Lab then turned to the Great Dane and asked, "Why are you here?"

"I'm a humper," said the Great Dane. "I'll hump anything. I'll hump the cat, a pillow, the table, fence posts; I want to hump.everything I see. Yesterday my owner had just got out of the shower and was bending down to dry her toes, and I just couldn't help myself. I hopped on her back and just started humping away."

The Black and the Yellow Labs exchanged sad glances and said, "So, guess it's balls off for you too, huh?"

The Great Dane said, "No... apparently I'm here to get my nails clipped!"
